A person, mechanically inclined, who fixes machines without regard for their 'stated operations' or 'proper repair procedures'.

Farm Mechanics must be used to repair machines which cannot be retreived through conventional means - such as machines which have gone beyond their stated tolerences, and would need to be 're-milled' to continue service... ( cracked engine blocks, shattered transmissions and differentials )...

The repairs seek to retreive a significant percentage of the machine's original function, while costing little, requiring few tools ( Farm Tools ), and being generally quicker ( but less 'reliable') than traditional repair methods.

The safety and 'transferability of operation' of the machine are ignored - once repaired in this way, one must continue to repair the mahcine in this way, and its operation might not be apparent or possible for those unfarmiliar with the repairs...

John's tractor threw the #4 connecting rod out through the bottom of the oil pan... the repair estimate was $6000, but the tractor was only worth $1200 - so John Farm Mechanic'd it back together, by welding the oil pan and modifying parts from another machine to fit. It now must idle 10 minutes when it starts before that piston begins to work, and it made a strange sound, but it drove forward and continues to work...
